Hey guys, this is my first forum post (You guys have helped me answer questions all of the time in the past, so I decided to join). I'm buying a MBP soon finally making my conversion from Windows. My desktop has a large amount of files that I need to transfer to my MBP. I bought a LaCie Rugged 500GB to do the transfer when it dawned that I might have a problem. So my question: When I plug the HD into my PC and transfer everything onto it, will the drive be able to just plug into a Mac and finish up the transfer, or will re-formatting the drive for a Mac mess it up?
